LlNOTYPE-MACHINE.

Specification of Letters Patent.

Patented June 25, 1907.

Application filed November 1, 1906. Serial No. 341,560.

To all whom, it may concern:

Be it known that I, RioHAnD M. BEDELL, of the borough of Brooklyn, county of Kings, and State of New York, have invented a new and useful Improvement in Linotype-Machines, of which the following is a specification.

My invention has reference more particularly to linotype machines of the character represented in U. S. Letters Patent Nos. 436,532 and 546,054, and generally known under the trade mark Linotype, wherein a vertical mold-carrying wheel is mounted on an arm projecting laterally from a horizontal slide, known as the mold slide, which latter receives motion from a vertical cam.

In a printing office it is frequently necessary to release the mold-slide from its operating devices so that the mold-carrying disk and mold may be drawn forward beyond their operative positions in order to give access to the back of the mold, the mouth of the melting-pot, and adjacent parts, to permit the substitution of mold-liners, 850. These operations require the presence of the attendant in front of the machine. Heretofore the slide-operating connections have been of such character that it was necessary for the operator to pass to the rear of the machine in order to effect the disconnection, then to pass to the front to perform the required operations, and finally to return again to the rear of the machine to establish the connections, after which he finally passed again to the front before the machine could be set in action.

The aim of the present invention is to overcome the trouble and loss of time incident to these operations, and to permit the operator to remain at all times in front of the machine.

To this end it consists in combining with the mold-slide and its operating mechanism, means extending forward in position to be operated by the attendant at the front of the machine, and adapted to effect the instantaneous connection and disconnection of the parts, and to maintain the disconnection during the required period. With the parts thus arranged, the attendant is enabled to lock and unlock the 1nold-slide, and to maintain the. parts in their unlocked position while standing in front of the machine where he can, at the same time, manipulate the mold-disk and slide as may be required.

I have shown my invention incorporated in the preferred form, and in connection with the ordinary parts of the Mergenthaler linotype machine.

Figure 1 is a side elevation representing the mold slide and adjacent parts with my improvement applied thereto. Fig. 2 is an elevation of the foregoing parts viewed from the. front, the mold disk being partially broken away. Fig. 3 is a View of a modification.

Referring to the drawings, A represents the vertical mold wheel containing the slotted mold a, and supported'by a central stud or pivot a.

B is the horizontal mold slide mounted in guides in the main frame and having at the forward end a lateral arm I), which gives support to the pivot of the mold wheel, this arrangement permitting the mold wheel to be rotated and also permitting it to be moved bodily forward and backward.

D is a vertical wheel having in the side face a cam groove.

E is a pendent arm or link, suspended by a pivot I at the upper end, and provided at the lower end with a stud or roller F projecting laterally into the cam groove and provided also with a second stud or roller G, projecting laterally from the opposite side andengaging in a notch H in the mold slide B.

It will be observed that the arm or link E serves as a connection between the cam wheel and the slide B, to which a reciprocating motion is imparted by the cam. The pivot I of the link E is supported in the forward end of a hand lever J, pivoted to the main frame so that by proper movement of the lever, the link may be raised and the roller G lifted out of the notch in the mold slide to release the latter.

So far as described, the parts are constructed and arranged to operate in the same manner as the parts indicated by like letters in Patent No. 546,054, and they require that the operator shall pass to the rear of the machine to effect connection and disconnection.

In applying my improvement, I pivot to the link E a second link K and extend the same downward to the rear end of a hand lever L, which is pivoted to the frame at Z, and extended forward to a point which admits of its being readily grasped and operated by an pressing the forward end of the lever, the link E may be raised and its stud G disengaged from the mold slide B, which is thereby released so that it may be drawn forward by hand to any required extent. When the slide is returned to its operative position, it may be instantly re-engaged. For the purpose of locking the lever and preventing accidental disengagement of the stud G, a toothed plate M is secured to the main frame as shown. This looking plate also serves to hold the connecting link in its elevated or disengaged position, leaving the hands of the operator free for use in turning the molddisk and in moving the disk and slide forward and backward to efiect their proper adjustments, as required in practice.

The essence of the invention lies in combining with the means for imparting motion from the cam to the mold slide, controlling means adapted to be operated from the front of the machine to release the slide.

It is manifest that the invention may be embodied in a great variety of equivalent forms, one of which is illustrated in Fig. 3, wherein the link E is dispensed with and the upper end of the link K adapted to carry Y studs or rollers F and G.

1. In a linotype machine, the combination of the main-frame, the mold-slide B, the mold-disk A carried thereby at the front of the machine, the actuating cam at the rear, connecting devices between the cam and slide, means for controlling the connecting devices extended to the front of the machine, and a locking device co-operating therewith to maintain the disconnection of the parts.

2. In a linotype machine, the combination of the main-frame, the slide B, the mold-carrying disk sustained by the slide at the front of the machine, the actuating cam, a connection E between the cam and slide, a handlever L extending to the front of the machine, a link K between said lever and the connecting device E, and means for locking said lever in position; whereby the operator, at the front of the machine, is enabled to connect the slide with and disconnect it from the operating cam, and to lock the parts out of connection.

In testimony whereof I hereunto set my hand this twenty third day of October, 1906, in the presence of two attesting witnesses.

RICHARD M. BEDELL.
